What kind of friction occurs as a fish swims through water

• sliding

• static

• rolling

• fluid

You push your book across the table, the sliding friction acting on the book

• equals the weight of the book

• acts in the opposite direction of the motion

• is greater than the static friction

Projectile motion is caused by the

• downward force of gravity

• downward force of gravity AND an initial forward velocity

• a final vertical velocity

The property of matter that resists changes in motion is

• inertia

• weight

• friction

• mass

Newton's 2nd Law says the acceleration of an object = the net force acting on the object divided by the objects

• mass

• momentum

• velocity

• speed

Your weight equals your

• mass

• mass divided by the net force acting on you

• mass times acceleration due to gravity

• pounds

Newton's 3rd Law describes

• centripetal force

• balanced forces

• action and reaction forces

• net forces

When an unbalanced force acts on an object,

• the inertia of the object increases.
• the weight of the object decreases.
• the object accelerates.

The SI unit of force is the

• Meter
• Joule
• Newton
• m/s

1 Newton =

• 1 m/s2
• 1 kg
• 1 kg m/s
• 1 kg m/s2
